Default That's different than unplugging it electrically.

You removed one of the pressure hoses so the car was unable to open the wastegates. That's why you got the charge pressure max limit DTC and the car went into limp mode to protect itself.

If you unplug the N75 (electrically), it defaults to an open path to the wastegate. Thus the car will only be able to make ~4 psi as that is the pressure required to open the wastegates (which is what the ECU does for limp mode... just turns off the N75).

Default just put it in stock mode or valet mode if you don't trust your dealer.

Haha, yeah, I know...I said "trust" and "dealer" in the same sentence... LOL!!

Default It's a good time, P->D, stall, crank, stall. IIRC 60% resulted in 4Krpm WOT shifts and painfully

slow accelleration, say 13+ 0-60. This was a stock tip allroad.
